This is the newest coco growing medium that CANNA has developed. It consists of a sophisticated mixture of coco grains, coco fibre and coco granules. Special about this medium is that it is dryer to control, as the medium contains more air. This results in plants taking root faster and consequently, in higher yields! Another advantage of the COGr slabs is that they are very manageable in storage and transport, because they have been pressed and dried. In addition they are suitable for reutilization
